Application filed March 30, 1923. Serial No. 628,836.

To @ZZ eti/710m 'it may concern:

Ee it known that l, EMIDIO Linnr, a citizen ot italy, residing at New Derry, in the county otI liestmoreland and State ot Pennsylvania, have invented new and useful lmprovements in Rail Joints, ot which the Jollowing` is a speciiication.

The object of this invention is to provide a particular type ot interlocking rail joint, by the use ot which iish plates and bolts may be dispensed with.

A turther object is to provideabutting rail ends with interlockingtongues constructed to permit ot removal and replacement ol a worn or broken rail by' merely loosening spikes at the point of juncture or the detective rail with the adjacent rails.

A still further object is to provide abutting rail ends with tongues and cutaway portions having curved surfaces, and reversely arranged, certain of the ends having` web portions between the reversely arranged tongues.

1With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described and claimed, being understood that inotliiications may be made within the scope of the claims without departing Jfrom the spirit of theY invention.

lin the drawings, Figure 1 is a perspective view showing abutting rail ends in Contact; Figure 2 is a top plan View, with the rail ends separated; Figure f5 is a side elevation, the cn ds being separated; Figure i is a vertical section on line 4.--fi oi- Figure 3; Figures 5 and 6 are end views showing respectively the horizontal opening and the horizontal web received by the opening.

rlhe abutting rails ot a track are designated 10 and 12, and rail 10 is provided with longitudinally extending tongues 14 and 15, each having concave and convex ysurfaces 16 and 16, the curves oi the respective tongues extending in opposite directions.

rlhe tongues ot the respective rail ends are in diagonally' opposed relation,-tongue 15 formed as in Figure 1, for instance, entending into a correspondingly formed recess oi the abutting railythe recess terminating in an approximately central horizontal plane,

is horizontal web 17 which tits between tongues 14: and 15 and acts as a guiding element during the swinging movement at the joint, so that the rail endsV will not bind, due to slight twisting act-ion, after the spikes are removed.

lt will be observed that the. rail cannot become loose long as the spikes remain in place, and that the use of. bolts, nuts, nut locks and lish plates is dispensed with.

In laying the rails, they are assembled in alinement and spiked to the ties, without other securing` devices, as indicated. ln replacing a rail the spikes ot the old rail are removed. and relative angular movement in a horizontal pla-ne is imparted to the rail ends, resulting in movement of the convex sur faces with reference to the concave surfaces, and immediate separation. The new rail is inserted by a reverse movement of a similar kind, and spiked down.

"What is claimed is z- 1. IThe combination oit abutting rail ends, one of the rails being formed with horizontally extending tongues, reversely arranged, and the other rail being formed with tongues arranged reversely with respect to those iirst named, the tongues ot the respective rails being in diagonally opposed relatioinand each tongue-being adjacent to an outer side or the rail, and a horizontal web formed between the tongues of one rail and itting between the tongues of the abutting rail. 1 y

2. The combination ot abutting rail ends, one-oi the yrails being formed with longitudinally extending vtongues reversely arranged and having engaging surfaces of convex form, and the otherot said rails being formed with tongues having enga-ging surfaces n the form of a compound curve, for cooperation with the convex surfaces.

3. The Combination of abutting rail ends, 5. one of the rails being formed with longitudinally extending tongues reversely v`arranged and khaving engaging surfaces of convex form, and the other of said rails curve, for cooperation with the convex surfaces, and a, horizontal web formed on one rail end and fitting between the tongues of the abut-ting rail end.
